Observers equipped only with a map, binoculars, and compass typically have a mean target location error of about how many meters?

Observers equipped only with a map, binoculars, and compass generally have a mean target location error of about 250 meters due to the limitations of these tools in providing precise positioning. The use of a map, binoculars, and a compass relies heavily on the observer's skills in reading topographical features and estimating distances visually, which can lead to inaccuracies.

Factors contributing to this mean error include the quality of the map, the observer's ability to interpret terrain features, and the inherent difficulties in accurately determining position without advanced technological tools such as GPS. The 250-meter figure represents a reasonable estimate that reflects these variables, illustrating the challenges faced in field operations without the benefit of more sophisticated equipment.
